If the lenght of a rectangle is 15 inches longer than its width whats an equation to represent the area of the rectangle?

Area = L x W = L x (L - 15) = L^2 -15L

To find an equation that represents the area of the rectangle, we need to express the length and width in terms of a variable. Let's use "w" to represent the width of the rectangle.

According to the given information, the length of the rectangle is 15 inches longer than its width. So, the length can be represented as "w + 15".

The formula for the area of a rectangle is:

Area = Length × Width

Substituting the length and width values, we have:

Area = (w + 15) × w

Simplifying the equation, we get:

Area = w² + 15w

Therefore, the equation that represents the area of the rectangle is:
Area = w² + 15w
